After Years of Perovskite Promises, Does This One Deliver? Take your personal data back with Incogni! Use code UNDECIDED at the link below and get 60% off an annual plan: http://incogni.com/undecided A California startup called Tandem PV says it has built the most efficient solar panel on the planet, hitting 30.4% efficiency where today's best silicon solar panels top out around 25%. That number came from the company's own lab, and the test module is barely bigger than a coaster. On the same day, a rival posted an independently verified result that beat it anyway. Perovskite solar panels have promised this kind of efficiency leap for years, but durability has always been the catch, and Tandem PV says it finally solved it. So is this really the world's most efficient solar panel? Or is Tandem PV's big claim more marketing than reality?
